Some people deliberately post conspiracy theories, especially political ones. (Think Russian disinformation.) These people are smart, and hard workers. If you create any kind of automated filter, they will find ways of saying it that won't get caught by the filter, or they will create new conspiracy theories. The only way around that is, rather than blacklisting conspiracy theories, you have to whitelist the truth. If that doesn't give you pause, it should.
